I'm so incredibly jealous. Lady Ada over at AdaFruit Industries has all these great toys to play and experiment with, and she's figured out how to do it while enriching all of our hacker lives and making a little money to find more great stuff.
The 'toy' that triggered this post for me is some conductive rubber stretch cord that acts as a sensor. It's like being able to pull on the end of a resistor and have it's characteristics change linearly as it gets longer and shorter. Way cool! And it is incredibly cheap. She's priced it at less than ten dollars for a full meter and even includes a pair of alligator clips and a 10k resistor. Science teachers, for example, could dice it up and have enough for each student to have a piece for experiments.
The only drawback that I can see is that the sensor takes a little while to recover after being stretched, though I guess that could be compensated for in some applications by using two sensors in opposition.
As usual, the AdaFruit website has a great related tutorial page so you can learn while having fun.
Lady Ada and Phillip Torrone stopped by Tokyo Hackerspace and were kind enough to explain the history, dynamic growth, and drive behind the Open Source Hardware movement. They are also the founders of AdaFruit Industries, a fantastic source for innovative and inspirational electronics and arduino kits that are actually useful.
I've been anticipating the release of practical head mounted display for years since they have tremendous potential for robot and remote telepresence applications. So far all of the designs have either been obtrusive and block the wearer's vision somehow, or they have had limitations that have precluded commercialization.
Now Brother Industries has announced they will roll out their AiRScouter transparent LCD display this Fall for business/industrial applications and hope to follow up with a commercially available version in the near future.

Technology development today faces some serious limitations that constrains its application and successful deployment, especially in non-traditional sectors. The two biggest limitations, at least from my perspective, are battery capacity/life and sensors. While there has certainly been a lot of progress in both areas over the past two decades, the core technology and design approach hasn't really changed very much.
In order to achieve radical improvements in the way we put technology to practical use some significant breakthroughs in both areas will be critical. Along those lines, one of the most interesting and surprising "thinking out of the box" sensor developments I've run across recently is the FuwaFuwa sensor module developed as a part of the Igarashi Design Interface Project under the auspices of the Japan Science and Technology Agency (JST) ERATO.
"FuwaFuwa" in the Japanese language is a kind of onomatopoeic word that roughly translates as light/airy/fluffy, and that's exactly what the FuwaFuwa sensor module does.
The original Keepon robot, developed by Hideki Kozima at Miyagi University in Japan, was incredibly cute and engaging, to the point that people just couldn't help smiling, laughing, and moving in sync while the robot danced to music or used it's built-in sensors to interact realistically with them.
The Keepon design concept was intended to explore the possibility that a simple emotive robot could help autistic children with communication and learning challenges. Most autistic children tend to be completely overwhelmed by the volume of input and sensory data involved in even the most basic social interactions. It's kind of like trying to take a drink of water from a fire hose. Kozima's insight, which turned out to be right on the money, was to reduce the flood of inputs to a minimum while packaging the robot in an appealing, friendly body.
